Precision-engineered surface can enhance silicon solar cell performance

Converting sunlight into electricity is the task of photovoltaic solar cells, but nearly half the light that reaches a flat silicon solar cell surface is lost to reflection. While traditional antireflective coatings help, they only work within a narrow range of light frequency and incidence angles. A new study may have overcome this limit.

Precision-Engineered Surface Boosts Silicon Solar Cell Efficiency

In a groundbreaking advancement poised to revolutionize photovoltaic technology, researchers have developed a novel metasurface-based antireflective coating that significantly enhances the light-trapping efficiency of silicon solar cells. Traditional flat silicon solar panels suffer from a critical limitation: nearly half of the incident sunlight is lost due to surface reflection, drastically reducing their overall energy conversion efficiency. …

AI designed nanostructure coating cuts solar reflection and boosts cell efficiency

Los Angeles CA (SPX) May 02, 2025 Conventional silicon solar cells lose nearly half their potential light energy to surface reflection, but a new antireflective coating could dramatically reduce that loss. Researchers have developed a precision-engineered metasurface composed of a single ultrathin layer of polycrystalline silicon nanostructures, enhancing light absorption across a broad spectrum and incidence angles.
